Description

Technical Field

[0001] The utility model belongs to the technical field of fire extinguishing, and in particular relates to a combustible gas fire extinguishing device. Background Art

[0002] Combustible gas refers to gas that easily reacts chemically with oxygen and burns on its own. Since common combustible gases have certain toxicity, flammability and explosiveness, once a fire occurs, it often causes serious personal and property losses. Several common combustible gases include methane, propane, hydrogen, etc. Combustible gas fires can be extinguished by carbon dioxide gas, but when the fire is large or it is inconvenient to approach the fire source, ordinary carbon dioxide fire extinguishers cannot effectively extinguish the fire. When the existing method of extinguishing fires by dropping bombs by drones is used, the fire extinguishing bombs are mostly water bombs, which are not suitable for extinguishing fires when gas is on fire.
